The above equation can be split into two components $$ \frac{sin\theta}{cos\theta} = \frac{sin\theta}{1} * \frac{1}{csc\theta} $$ 2. Referring to the list of trig identities, we know that $\frac{1}{csc\theta}$ is equal to $sin\theta$. - +$$ \frac{sin\theta}{1} * \frac{1}{csc\theta} = sin\theta * sin\theta $$ +3. Simplifying further, we get: +$$ sin^2\theta $$
